Laser inspection system Head Check

automaticcrack detectionfor railway applications

The new generation rail steels are of such high quality and are so resistant to abrasion that material wear is no longer sufficient to prevent the growth of cracks appearing in the rail surface such as "head checks" (defects occurring at the gauge corner of the rail). This condition is a potential threat to rail integrity. Automatic and early-stage detection and precise localization of head checks when rail grinding is still a possible solution. Head Check Detection Head Checks Detection System is a high accuracy machine vision system able to identify head check defects in their early stage, when they can be removed by processing the surface of the rail, for example by re-grinding. System is able to identify sub-millimeter defects at an inspection speed up to 120 Km/h in any light and weather conditions.
